What to expect with uncoated Accoya


Accoya weathering

Accoya weathering

Wood is an organic material, and it changes over time as it reacts with the sun and the rain, developing new colours and textures: a process known as weathering.

Accoya, as a natural wood product, is no different

Like other wood species, uncoated Accoya wood will weather over time to an elegant slivery grey colour when left outside and exposed to the elements.

Unlike other woods however, weathering does not affect the durability, stability or performance of Accoya.

During the weathering transition process the surface colour of Accoya can appear patchy due to the different levels of sunlight and rain coming into contact with the wood, but over time it evens out to a beautiful silvery grey effect that lasts for decades to come.

Because Accoya has such great dimensional stability, coatings are not so stressed by shrinking and swelling forces that affect all other types of wood – meaning they last and look better for longer. For certain applications such as windows it is industry standard for frames to be coated to protect the other parts of the window fittings and mechanisms.
